'Ifhis invention relates to soap dispensing ap'- paratus of the type used primarily for measuring out small quantities of hand paSteS, such. as yprotective pastes or soap, in washroomslavatories y and similar places.V ,y

The invention 'has for its main object rtojpro-r vide a storage and dispensing container combining simplicityof construction, positive discharging actionyindicating means for measuring the quantity of hand paste dispensed and 'rigidity of mounting. l i

Otherobjects and advantages will beapparent for an understanding of the' drawings and their accompanying description.

In Figs. l and 2 paste dispensing apparatus embodying the features of my invention and generally indicated by the numeral I is shown removably mounted on a wall or beam 2 by means of blocks 3 and 4 cut to form a dovetail joint as shown. Block 4 and the dovetail groove of block 3 are tapered to ensure firm interlocking of the cooperating joint parts. In addition, a set screw (Fig. 3) serves to prevent easy withdrawal of the dispenser from its mount.

The dispenser I includes a storage compartment or reservoir 6 consisting of a cylindrical wall member 1- and a bottom plate 8 fixed thereto. The bottom plate 8 is provided with a radial slot 9 partially covered by an upturned overlying shearing edge Ill of a deflector plate II, which plate is fixed to the bottom plate 8 by rivets as shown in Figs. l, 3 and 4. In addition the bottom plate 8 contains a bearing socket I2 to receive the lower end of a Shaft I3 which is' carried by and extends downwardly from a cover l z'ciaims. (craze-'ssi j member I4. The cover I4 is provided `witha hubl portion I5 suitably yproportioned to properly y.journal said shaft I3. A shoulder I6 is provided onthe shaft 'I 3 to prevent accidental withdrawal of said shaft through its bearing. A `handle I1 is secured to shaft I'3,.as by a locking pin I8 and container'the cover I4 is jprovided with a downwardly projecting portion 2| vwhich nts the inner bore of the walls 1 and which contains locking means as shown in Figs. 5 and 6. In Fig. 5 a spring pressed lock pin 22 extends through a bore 23 inthe wall 1 when the cover and conftainer are in locked position; and diametrically opposite and neark the yupper edge of wall 1 a pin 24 fixedin said wall and protruding inwardly cooperates with a locking groove 25 formed in portion 2l of `cover I4 as shown in Fig. 6.

In Figs. l, 2 and '1 means for providngan y indication of the angular movement given shaft I3 are shown comprising a coarse vertical iiuting or grooving 26 formed in the outer surface of hub I5 and a spring pressed ball 21 held in a bore 28 formed in one of two enlargements 29 depending from -handle I1, spring 30 being compressed between the ball and a threaded plug 3|. rBall 21 imparts only a slight restraining action o n the shaft I3. However, if shaft I3 is rotated, the intermittent displacement and return of the spring pressed ball results in an audible signal as the ball moves in and out of the grooves 2B in turn. In addition to the audible signal just described, the impact of the spring pressed ball 21 even though slight, results in a slight jarring action which is imparted to handle I1, which jar may be felt by anyone grasping and turning said handle. An audible and touch sensitive signal is thus provided which is indicative of the amount of paste dispensed without the necessity of visual inspection. Since the dispensers will usually be mounted approximately at waist height for convenience of operation, visual inspection is inconvenient and an audible or touch sensitive signal is of substantial advantage to the efficient and economical operation 0f the dispenser.

A modified arrangement for indicating the extent to which the shaft I3 is turned is shown in Fig. 9. As there shown the hub I5 is recessed at 31 to receive a coarse ratchet 36 fixed in the shaft I3 and engaged by a spring pawl 38 secured to the wall of the recess 31. The movement of the pawl 38 over the coarse ratchet teeth gives an 3 audible and tactile indication of the rotation of shaft I3 similar to that previously described.

Fig. 8 shows a modied form of discharge slot in which the deilector plate is eliminated, and a shearing edge 39 is formed from a slightly upturned portion 40 of bottom plate 4I. In this modification thematerial of bottom plate 4I may be thin enough to permit slot 42 to be formed by punching the material of said plate rather than by cutting or slitting. In this way the formation of slot and shearing edge may be accomplished in one operation.

In use, the dispenser I is lled or partially lled, with hand paste, fluid enough to level off in the bottom o'f the container, but are viscous enough so that they will not flow by their own weight through the restricted opening of the discharge slot 9, Thus we have the container lled with paste in which is suspended the paddle shaft I3 and paddle I9. Rotation of the paddle shaft and paddle by means of the handle I`I results in the rotary displacement of the body of paste which surrounds said paddle. The Vpaste nearest bottom plate 8 is deilected by shearing edge II) of the deector plate I I into slot'l 9 through which it is discharged in a thin wafer-like ribbon. The discharge action will continue as long as the paddle is rotated.

The action is the same for the modified form of discharge slot shown in Fig. 8. In this case however the shearing edge 39 of the upturned portion 40 deflects the paste into the discharge slot.

What we claim is:

1. A hand paste dispenser comprising a cylindrical reservoir for the paste having a bottom provided with a constantly open narrow discharge opening, means along one edge of said opening to guide the paste through the opening, a removable cover member provided with means for locking the cover to the reservoir, said cover having a centrally positioned outwardly extending hub, a shaft rotatably mounted in said hub and held against axial movement relative thereto, said shaft extending downwardly into the reservoir, a bearing socket iixed to the bottom of the reservoir for receiving the lower end of said shaft, a thin ilat paddle xed to the lower portion of said shaft and extending transversely thereof Pastes of this type are` in a vertical plane, the lower edge of the paddle being positioned closely adjacent the bottom of the reservoir, a handle xed to the shaft outwardly of said hub, and means rotatable with the shaft and engageable with means carried by the hub to form an audible and touch sensitive signal means to indicate theamount of rotation imparted to the paddle shaft.

2. A hand paste dispenser comprising a cylindrical reservoir for the paste having a bottom provided with a constantly open narrow discharge opening, means along one edge of said opening to guide the paste through the opening, a removable cover member provided with means for locking the coverl to the reservoir, said cover having a centrally positioned outwardly extending hub, a shaft rotatably mounted in said hub and held against axial movement relative thereto, said shaft extending downwardly into the reservoir, a bearing socket iixed to the bottom of the reservoir for receiving the lower end of said shaft, a thin flat paddle fixed to the lower portion of said shaft and extending transversely thereof in a vertical plane, the lower edge of the paddle being positioned closely adjacent the bottom of the reservoir, a handle fixed to the shaft outwardly of said hub, and having a depending portion opposing the outer surface of the hub, said surface being coarsely iluted, and a spring actuated ball member carried by said depending portion and engaging the flutes on the hub to provide an audible and touch sensible indication of the amount of rotation imparted to the shaft.
